HORSE SHOE To all whom it may concern:

Be it known that I, Josevi-1 KALM, a citizen of the United States, residing at Missoula, in the county of Missoula and State of Montana, have invented a new and useful Horseshoe, of which the following is a speciication.

This invention relates to horse shoes, and more particularly to the kind designed to be attached to the hoof of the animal without the use of nails.

It has for one of its objects the construction of a horse shoe equipped with a novel form of heel and toeplates adapted to engagey the locking member.

Another object is to provide an improved form of locking strap designed to be secured to the hoof of the animal and to the shoe.

With these and other objects in view as will more fully hereinafter appear the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and ni ore particularly pointed out in the appended claims, it being understood that various changesin the form, proportion, size and minor details of the device may be made without departing` from the spirit or sacriiicing any of the advantages of the invention.

In the accompanying drawings forming part of this specification Figure 1 is a perspective View of the shoe and locking strap. Fig. 2 is detailed perspective of the front portion of a modified form of locking strap. Fig. 3 is a front elevation of a modified form of toe clip. Fig. l is a modified form of nail .f to prevent displacement of the shoe on the animals hoof, and Fig. 5 is another modilication of the same.

Similar numerals of reference are employed to designate corresponding parts throughout.

In carryingout the invention 1 provide a horse shoe with a toe clip having on its outer face projections or teeth, and on the upper face ofthe shoe adjacent to its opposite terminals heel clips are formed each of which is provided on its inner face with a lug having a suitable channel or groove formed therein provided with teeth. With this construction a locking strap is provided which is designed to embrace the hoof of the animal, having inwardly turned teeth on its lower edge designed to enter the hoof, and provided aty its Specification of Letters Patent.

terminals with teeth to engage the teeth of the heel clips.- The locking strap is further provided at its central portion with spring arms which are designed to be forced under the teeth of the toe clip whereby the shoe is firmly secured in place.

By referring now to Fig. 1 it will be seen that the shoe 1, is provided on its lower face with. the usual toe and heel calks 2 and 3, and on its upper face, and adjacent the outer edge and extending substantially throughout the entire length of each limb are upturned prongs 4t. These members are upstruck as clearly shown, and their function is to enter the lower face of the hoof, similarly to the ordinary nail, so as to prevent lateral and longitudinal displacement of the shoe while on the hoof. r1`he form of toe clip employed consists of two vertical bars 5 and 6, formed integral or otherwise, and secured to the upper face and at the outer edge of the shoe. These bars are disposed on either side of the center of the shoe and are slightly curved or inclined to the rear to conform to the incline of the animals hoof. Adjacent to the upper end of each bar and on the outer face is formed a forwardly projecting lug 7 constituting a tooth, the function of which will appear later. The vertical clips or heel plates S and 9 are disposed on the upper face of the shoe and at the opposite ends thereof and have their outer faces coincident with the outer face of the shoe and their rear ends inclined forwardly from the rear upper edges of the terminals of the shoe. Each heel plate is provided on its inner face and adjacent its upper end with a thickened portion constituting lugs 10 and 11. These keepers or lugs are suitably recessed or channeled on their lower end, throughout their entire length, and the door of each channel is suitably notched so as to form teeth 12. The locking strap 13 is preferably formed of a single piece of resilient metal of the approximate shape and size of the shoe 1, and on its upper edge and at either end a row of teeth 1-1 is formed, corresponding in number and size to the teeth 12 of the heel plates. The strap is at its middle longitudinally recessed as shown at 15 for a portion approximately equal to one-third its length, the opposite ends of the recess being equidistant from the center of the strap. The portion constituting the upper wall of the recess is divided at its center so as to forni spring arms 16 and 17. These arms are sprungin-v of the toe plate as will appear later.

ln the use of the device thus far described,

it is designed iii-st to apply the shoe to the hoof ofthe animal in the ordinary inannerjand after the saine has been accurately adjusted, the foot is loweredand .the pressure on the prongs il, due to the weight of theaiiiiiial, will ordinarily be suflicierit to forcethe prongs into the hoof.v The lool;-v4 ing strap is next applied by inserting its opposite terminalsinto the channeled lugs, until' the teeth la engage the teeth 12, during this operation it is designed that ,the poi'- tion constituting the lowerhalfY 18. at the central orfront end of the strap, shall be dif iecltlyin front of :theteeth 7 Aof the toe plate, andthespringarms.16 Land 17 above "teeth, so that when theteeth 12 and 14 are mayil be Iemployed to forcethe body of the strap downwardly. Y mentV ofthe strap will .cause the spring arms 16 an'dxlr, whenriding over theupper ends ofthjeteeth 4",to movefoutwardly, and this they will continue to do vuntil moved downward su li`iciently to pass the teeth when,

owing to their inward curving they will snrini beneath the teeth, thuscom leting.

l e P thefasteninglof the slice.

It'xwill be observed that oppositeportions 19 of `the lockingstraplying forwardly or inwaidly'of the teeth 1st are curved sinuous'lyfora distanceapproximately equal to;

theflength of each row of teeth, and these sinuously curved portions are, throughout their iniddles, providedv with similarly shapedopenings lor recesses 20. The func-Y tion of this construction is to, lessen the strainon thel teeth, 12 land 14, by permitting a longitudinal yielding of the Estrap when forcingv thelatter over the toeclip. Inorder further to ysecure the locking` strap against displacement, its lower edge is suitably notched so as to forni teeth 21. These teeth are flexed slightly inward so that when the strap is forced downwardover the toe clip they willfasten in thehoof of the-anis mal.

Figs. 2 and 3 show a modified form of toeclip and locliing'strap. The posts 22 and 23 of the toe clip (Fig. Yare identical .to those shown in Fig. 1 with the exception that each post is provided with a series of downwardly projecting teeth or lugs 24 arranged lin a Vertical plane on its outer face. The form of locking strap employed in connection with this toe clip is similar to that already described with the exceptionv that thespring arms25 and 26 are provided with twoor morelongitudinal recesses27, the

metal at the upper side of eacliof these re-vl cesses isy inclined slightly outward, and the lowerX edge ofthe strap beneathI the llower engagement, a suitable clamping tooll This downward movecause tlieupstruck fasteners l to bend. In

the application of the forni illustratedin Fig. il, suitable openings areforined inthe YA shoe. rlhe fastener 28 which is substantially .vedge shape, is provided on its opposite sides with barbs .or serratio-nsy 29,. and `is longitudinally divided fora portionof its length .as shown at 30, sotha-t when the shoehas been adjusted to the aniinals hoof the fastener is driven-in, in vany'wellfknown manner. A suitable. tool is next forced into the opening 80 causing the. sides to spread-1 and the serrations or barbs 29 to'engage'thez 85 walls of the; openings.`

Fig. 5 shows a section of-horse shoepro-nv vided with an opening similarfto that shown in Fig. 4l. The form. of fastener employedf therein consistsof a wedge shaped member 31, of a sizeto lit; snugly within theopening" and having lateral projections or lugs 32r disposed at .substantially its horizontal cen ter.. in the application of this form,rthei fastener is-inserted in the opening `before195 applying thershoe to the hoof, and the lugs 32, restingon the upper face ofthe shoe, prevent thefastener from falling through"-v the opening. A longitudinal opening 33 is forinedin the lower. portion which perinitsilOO it to be spread so as to bind tightlyagainstff the walls of the opening. It is to be understood that thesefasteners arenot-intended for any other purpose than to'preventfslid- I ing of the shoe on the hoof.

That is claimed is l. Thecombination with a horse shoe havingv atoe clip `provided with teeth on itsf outerface and heel clips having keepers on` their opposed inner faces, of a fastening strap terminally provided with means-tof engage lthe keepers and intermediately provided with yspring` armsto engage the'teeth of thetoe clip.
